Given numbers are 455, 234, 289

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(455, 234) = 8190

GCD(455, 234) = ( 455 x 234 ) / 8190

= 455 / 234

= 455

Step2:

LCM(13, 289) = 3757

GCD(13, 289) = ( 13 x 289 ) / 3757

= 13 / 289

= 13

So, Greatest Common Divisor of 455, 234, 289 is 1
